Healthy volunteers are observationally wearing an intraoral device with bovine tooth samples once for two hours. Afterwards, Calcium release from the bovine enamel and dentin samples is measured after extraoral erosion.
Total protein concentration within the formed salivary pellicles on the bovine samples is determined. Further Salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity, albumin and total protein content as well as concentration of inorganic calcium, phosphate and fluoride) are being measured.
The aim of this study is to investigate whether gender differences in the salivary composition correlate with predisposition to erosion.

The aim of this study is to investigate whether smoking is associated with changes in salivary composition and/or predisposition to erosion. Healthy volunteers are observationally wearing...
The aim of this study is to evaluate the influence of several factors (light, extrinsic stain removal and operator's experience) in tooth color assessment. Tooth color will be assessed by ...

Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth ...
The purpose of this study is to assess tooth health by using a pulse oximeter which measures the blood flow within the tooth. This method is not currently being used in dentistry. We hypot...

The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (From Jablonski, Dictionary of Dentistry, 1992, p2)
The wearing away of a tooth as a result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It is chiefly associated with aging. It is differentiated from TOOTH ABRASION (the pathologic wearing away of the tooth substance by friction, as brushing, bruxism, clenching, and other mechanical causes) and from TOOTH EROSION (the loss of substance caused by chemical action without bacterial action). (Jablonski, Dictionary of Dentistry, 1992, p86)
Devices used for influencing tooth position. Orthodontic appliances may be classified as fixed or removable, active or retaining, and intraoral or extraoral. (Boucher's Clinical Dental Terminology, 4th ed, p19)
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.

A tooth from which the dental pulp has been removed or is necrotic. (Boucher, Clinical Dental Terminology, 4th ed)
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
